删除phalcon中的多个选定行答案

【问题标题】：Delete multiple selected rows in phalcon删除phalcon中的多个选定行
【发布时间】：2016-04-11 04:56:12
【问题描述】：

我想通过单击删除选定的多行或所有行。但我想不通。我怎么能用我的代码做到这一点？请编辑我的代码以获得预期结果。

这是我用于选择所有行的 jquery

[Jquery]
function selectAll(status){
$('input[name=slId]').each(function(){
    $(this).prop('checked', status);
});
}

如何让 id 进入控制器以执行删除过程？我的 jquery 没有发送任何 id，我用 var_dump 测试它显示为 NULL。

[Controller]

public function deleteAction()
{
    if($this->request->isPost())
    {
        if($this->session->has('uname'))
        {
            $id = array();
            $id = $this->request->getPost('id');
            $data = Blogs::findByid($id);
            if(!$data->delete())
             {
               echo('Unable to Delete');
             }
        }
    }
}

{{ form('blog/delete', 'enctype': 'multipart/form-data') }}
<table class="bloglist">
<thead>
    <tr class="fbold">
           <td>
{{check_field('checkbox','id':'sall','onclick':'selectAll(this.checked)')}}     </td>
        <td>Title</td>
        <td>Author</td>
        <td>Views</td>
        <td>PublishedOn</td>
    </tr>

<tbody>
{%for all in ball %}    
    <tr class="zebra">
        <td>{{check_field('slId', 'class':'slId','id':all.id)}}</td>
        <td class="tal">{{all.btitle}}</td>
        <td>{{all.bauthor}}</td>
        <td>{{all.views}}</td>
        <td>{{all.datetime}}</td>
    </tr>   
{% endfor %}        
</tbody>
<tfoot>
    <tr>
        <td colspan="6">{{submit_button('DELETE')}}</td>
    </tr>   
</tfoot>
</table>
{{end_form()}}

【问题讨论】：

您的表单提交给blog/delball，但您的删除代码在您的deleteAction()中
更新我的答案。但实际上它没有得到 ids 以及如何处理多个 ids 数组？
不确定你的控制器代码但是jquery中有语法错误，$('input[name=slId]')应该是$('input[name="slId"]')注意名称值的双引号
您的控制器请求参数id，但您的HTML 没有名称为name="id" 的元素。除了 Volt 代码，你能给我们提供 HTML 代码吗？
也将 jquery 更改为您的指令。但它没有向控制器发送 id。 var_dump 显示 NULL

【解决方案1】：

你应该用declared method：

{{ form('blog/delete', 'method': 'post') }}

你正在使用它来接收数据：

$id = $this->request->getPost('id');

要测试您是否通过 post 请求控制器，您可以在控制器中扩展您的代码：

if($this->request->isPost())
{
    // ...
} else {
    throw new \Exception('no_post');
}

我只是认为它是这样的，它按预期工作！

[控制器]

public function deleteBlogAction()
{
    if($this->request->isPost() == true)
    {
        if($this->session->has('uname'))
        {
            $ids = $this->request->getPost('item');                
            foreach($ids as $item)
            {
                $blogs = Blogs::findFirst($item);
#Erase Post Related Image                    
                $uploadPath = 'uploads/blogs/';
                $defaultImg = $uploadPath.'empty.png';
                $getImg = $uploadPath.$blogs->bimage;
                if($getImg == true AND $getImg != $defaultImg)
                {
                    if(@unlink($getImg) == false)
                    {
                        echo('Uploaded Image Cannot Delete');
                    }
                }
 #Erase Post Related Comments      
                $deleteC = Comments::findByentry_id($item)->delete();
#Erase Blog Posts                    
                $deleteB = Blogs::findFirst($item)->delete();
            }
            if($deleteC != false AND $deleteB != false)
            {
                $this->flashSession->success("The post &amp; related comments has been deleted.");
                return $this->response->redirect('blog/getBlog');
            }
            else
            {
                $this->flashSession->error("Sorry! We are unable to delete.");
                return $this->response->redirect('blog/getBlog');
            }
        }
        else
        {
            $this->flashSession->error("Unauthorised Access!");
            return $this->response->redirect('blog/getBlog');                
        }
    }
    else
    {
            $this->flashSession->error("Request May Not Posted.");
            return $this->response->redirect('blog/getBlog');            
    }
}
